Do you think it will make much of a difference performance was. IE do you think im making enough power that those won't provide sufficent flow?

 

no idea about that. most people say completely pulling the cats is only worth a few hp, i would rather have the stock cat's than those bullits you have there. i think the dynomax bullits would flow prety much like a strait pipe.

 

Im not really sure what i want to do now, I'm pretty sure my cats are pretty restrictive because they are only a 2.25 inlet and outlet diameter. Also isn't the few hp gain on a bone stock engine?

 

I believe that Summit mufflers are made by Stainless works http://www.stainlessworks.net/ , one of the sponsors. I have a pair of stainles works chambered mufflers and love them.
